Convert Feet & Inches to Metric
Why This Converter Matters in Commercial Vehicle Design
In the UK transport industry, both metric and imperial measurements are in constant use. While manufacturers like Don-Bur design trailer bodywork using metric measurements, real-world infrastructure and industry conventions often require quick and accurate conversion to imperial — especially when considering trailer height.
For example, bridge clearances are almost always displayed in both feet/inches and metres. Ferry operators, logistics hubs, and even route planning tools still use imperial figures to set limits and avoid damage. In day-to-day operations, it's not uncommon to hear drivers refer to their trailer as being “13 foot 6” — even though the engineering drawings specify 4,115mm.
This dual-unit system makes this converter tool more than a quick reference — it’s a practical solution to a real industry need. We use it regularly during the trailer design and spec process, especially when dealing with:
- Maximum trailer heights vs bridge strike prevention
- Pallet aperture sizing and internal load clearances
- Double deck trailer configurations
- Compliance with ferry operator requirements
As an engineering-led manufacturer, accuracy is key. Even a few millimetres can make the difference between passing under a bridge or causing a major incident. That’s why this tool exists — and why it remains one of our most visited resources.
